My little birdy
My little birdy works within the administration of airworthiness approval.
Little birdy cheeped that the reason for doing this was because of the recent saga/fiasco with Yak maintenance and that there was also some concern that certain private operators were using the N reg whilst not always adhering to FARs.
Like I said in my initial post, it is unsubstantiated but it is the first time that I have heard anything of the like and alas I have been around GA a long time!
